Binary and Nonbinary Transgender Patient Experiences Accessing Gender-affirming Top Surgery.

Background: Transgender and gender diverse (TGD) individuals face barriers when seeking top surgery, or bilateral mastectomies, as part of surgical transition, leading to delayed care and adverse health outcomes. Understanding differential experiences between nonbinary and binary patients is crucial for improving TGD patient care, but this distinction is seldom made in the current literature. Methods: This single-center cross-sectional mixed-methods survey study conducted between 2022 and 2023 enrolled all consecutive TGD patients undergoing top surgery. Significant differences between datasets were determined by two-sample unpaired Results: Thirty-seven binary and 71 nonbinary patients completed the survey. Lack of funding, long wait times within the healthcare system, and long wait times to access surgery were the three most impactful barriers for both cohorts. Nonbinary patients were more impacted by a lack of TGD-friendly surgeons and community physicians, prejudice from surgical center staff and community doctors, and employment concerns. More binary patients desired a "masculine chest" and to stop using a binder. The nonbinary group more frequently desired a "smaller chest" and had greater variability of surgical goals. Conclusions: Binary and nonbinary TGD patients both experience barriers to top surgery; however nonbinary patients may experience distinct barriers and have differential surgical goals. It is important to discuss specific surgery goals and offer top surgery options beyond bilateral mastectomy with nipple grafting, especially with nonbinary patients.
